APS Airsoft CAM870 MkIII Complete Guide & Review 

"My wife happens to collect combat shotguns."

This is 40 minutes of stellar technical and historical info about the real gun and the airsoft replica, what a treat! Killer video!

Love how you recreated the "T2 Sarah Conner" M870, without rubbing it into our faces. Important video, i come here from time to time to get vital infos. Because of you guys, I grabbed myself an Striker 12, last year. Best decision ever.

I love that I watched a full 40 minute video on an airsoft shotgun that I will never get for a sport I don’t play. Well made video!

Living in Taiwan for nearly 6 years at this point, and airsofting here and in the UK beforehand for a total of 18 years... The "dog and pony show" is one I've seen on rerun, as nauseum, in multiple languages... They are terrified of the idea of people converting airsoft guns to fire live rounds in both my homeland and my current home, and no amount of qualified engineering types or people who actually know about firearms and replicas thereof is - apparently - ever going to placate them... The APS MkII made it to Taiwan OK, but was just awful due to the gas then being stored in the bolt itself, thus eliminating the ability to continually feed rounds as you had to reload the bolt's gas separately. Sad. Times.

Never knew there was someone that can make so much info on this shotgun. I do love shotguns but got scared of the horror stories everyone says about gas shotguns in airsoft. So what I use is a simple Cyma 870 spring shotgun. Works for me and is cheap but man am I a sucker for those CAM870s

This is the review I’ve always wanted. I’ve been on the fence about a cam system for so long

History, technical specifications and great modifications. Fantastic as usual.

The CAM870 has been on my wish list for a long time, but other things took priority. Thanks so much for the review! I can reference this video when I eventually get it!

Please keep making videos. Your the only legit airsoft reviewer ive ever seen and you just eared a new subscriber

Best channel, had the 870 version for years

This is the absolute and most in depth review of the CAM 870and I really appreciate your expertise. I love the CAM 870 but this “warts and all” video is truly what everyone needs to make the best decisions. Thank you so much.

Best video so far about APS m870, saved in my useful videos too , Great work Sir!

You guys are a godsend to the airsoft community. I have the medium length (I believe it's the SF version according to APS' nomenclature, iirc) and will be putting a Pachmayr repro pistol grip to use it as a breacher. When the shotgun will need some tinkering, I know where to turn to 🙏🏻

This video has been incredibly in depth and helpful, thank you so much!

In the airport right now, thanks for making my layover just a bit better.

I absolutely love how technical your reviews are, especially comparison to the real steel counterpart. Any chance you'll make a review on SCAR platform, either WE or VFC, or a comparison of both?

Quality content as always! I really like my CAM870

Love the review, I have had a love hate relationship with my 870 cruiser. I had the firing pin fuse itself /get stuck in the bolt to the point where i ended up just buying a new bolt and swap it in there. I recently bought the street sweeper, its so much fun.

From my reddit response: Hello, I use a Cam870 and other shell ejecting shotguns and love the info presented. The bits about reliability is especially useful. I plan to do some of the modifications you have done, especially with getting the shells to feed consistently. For gassing shells you can use an HPA tank instead of co2. Either use those co2 adapters or APS makes a tank version of their fill nozzle although I would recommend not using APS as their fill nozzles break easily. You can use a remote paintball line so you don't have to hold the whole tank. I saw another guy make a video way back and he used super high pressure air for 1100+psi for much more power. The bit about buying separate hulls is interesting and a pretty good idea. I like to keep the hulls on to minimize the time required to prep shells. You can use a nozzle extension and teflon tape to help seal. I carry my shells on a 12g bandolier with elastic bands. They hold on to the shells well and it's a once piece accessory that takes minimal time to put on or off. I use a dump pouch for empty shells. I don't use a shell holder. If I have the time I will just fire one shot and then eject the shell in the air and catch it by canting the gun or ejecting it straight into my hand. Before I tried to do the paper cut outs like you did but noticed that every now and then the top paper came loose and would spill BB's. Sometimes either in the gun itself or on my body where they were stored. APS makes flower wads which is a one piece design instead of the older two piece wad/topper design. I may give it another shot with that loading tool. Maybe it would make it more consistent. I haven't tested my shotgun tracer unit to see if it would work with the APS but that would be interesting for cqb to see a glowing cloud of BB's headed towards enemies. Overall I have the same conclusion as you, this works differently so you got to do things different but it's fun and has the benefit of a huge amount of BB's per trigger pull.

If we could get a Ghk ak Guide like the AUG one at some point that would be incredible! Also on a side note I absolutely love how you do the videos and have learned a lot as a new Gbbr because of them ❤

Awesome video! Id definitely look at the cam870 for a shotgun for sure! Would be an awesome tool for cqb!

I have a MkII receiver with a MkI bolt. It is one of my favorite airsoft guns, and I have been considering picking up a MkIII just to have another.

Thank you for this awesome in depth review. I got the mk3 salient arms version last week and it seems that version is different or they have made some changes to them overall. The bolt is removable from the front without removing the magazine tube and the 2 tube clamps (as long as you remove the bolt stop in the reciever of course) , the extractor looks like the modified one you show and though I'm not sure if the "elevator" dog bone is altered it does work flawlessly even when inching the pump forward slowly. If you are interested I can take some pictures of relevant parts like the trigger group, bolt etc.

I love my super long competition version with magpul furniture for open field use. Instead of CO2 I use hpa with a Ninja Air HPA Pro V2 SHP Series Tank Regulator which outputs 1100 psi. It can be tuned down but at the default pressure is pretty close to liquid co2 power. The only issue I’ve seen is if you aren’t careful and fill the shell at an angle you might bend the fill valve. I just 3d printed an adapter to hold the shell straight and haven’t had any issues since. Using a paintball co2 remote line and threading the top part of a 12gram co2 loader to it makes for a nice way to charge shells without having to buy co2 tanks.

Very nice video, thank you

Top tier review as always! I always learn something useful when watching your videos. It's a bit sad that the MK2 doesnt seem to be that good, I like the idea of having the gas in the bolt or stock and running 3D-printed shells. What is your view of the Dominator DM870? Given the CNC'ed steel parts, it does look like a better quality product on paper but you never know if the whole package is any good.

love your content. will there be a video talking about ak gbb in the future? maybe in general and or comparing ghk and we tech

another killer video

Oh and i just subscribed to support as this was so helpful i have followed every step so far ..just need to get a Co2 adapter for my paintball tank

Great video, very informative Where to get the overfolding stock?

very amazing job 👏👏👏👏👏👏

very good video!!

Hello, I just bought the Remington M870 express stock and handguard to put on APS cam870 mk3 classic, are they compatible?

Would be awesome if you could do a video on the marui mp7 ! Even if its not quite full scale

Excellent, thank you

Hello, very nice video ! I have a question, how much Material do you have removed on the Top of the magtube retaining pieces ? And is a real dog leg works fine with all other Aps parts ? Thank you very much !

My CAM870 very hard to load the shells into the mag tube, because the shell's rim is rough after a few rack, and there is a white cut-O-ring at the start of the mag tube that prevent the shell from entering smoothly. I don't know what it is for, so I haven't taken it away just yet. Do you have any advice for it? I don't wanna file the shell's rim smoothly, cuz it might cost the shell-cycling functionality

I have 5 airsoft shotguns... and one rifle. I keep drooling over the CAM and the Marui breacher

Hello! Just wanted to ask where you picked up the hole punch? Most of the ones I’m finding on Amazon and such don’t pop out the paper disk as easily or efficiently and I’d love to get the same one you demonstrated with Thank you!

I think bring Marui 870 to game site will be much easier but when you talking about fun, shell eject for sure!

I wonder if you could use two of these to make a double barrel break action

You make me miss my dm870 that I converted to take cam870 shells.

Where can I get the co2 fill adapter? Is it the same as the propane fill adapter?

I have a dumb question. Would furniture be interchangeable between the real 870 and the airsoft version? I've got a little project going with an 870 clone and I dont want to pay $500 for a factory folder. I was considering using one of these airsoft versions.

One thing I hate the CAM870 most is they never have 14-inch nor 18-inch barrels, which are commonly use by military/LE, they only offer 12.5-inch(too short) or 20-inches barrel (too long). Since most of the people like to build their airsoft in a military/LE setup, with the barrel length problem , it's hard to build an actual combat setup with a CAM870, it just like a dumb joke.

How do you get APS parts here in the states? On their website it says “we do not ship gun parts to your country, please cancel your order!” and their only listed distributor in the US is Evike, which seems locked into the MKII system.

My 870 was from 2007 and it was reliable 90% of the time. My turkish winchester is 100% reliable which really tells you how far remington fell before falling into the grave.

Have you tried the flower wads? Yeah the PPS catcher is in-obtainum atm, been looking for one for over 6 months …. But my Google fu is letting me down

I'm not a shotgun guy but it's fun to see what our shotgun wielding friends are dealing with.

Have you tried using citristrip on the stock? I know it's messier and a bit more work than you're probably wanting but it may work better.

I had one for a long time never used it right until now. Would you guys ever e interested in making a video converting a dominator to use APS shells. I wanna do it, don't know how.

ASG makes plastic 4.5mm .13g BBs. Have you tried those? I miss the days when I took my MK2-turned-MK1 to a CQB field. Having someone on the receiving end comment that "it was like a grenade went off" (with your original 17-shot load) was a highlight in the years that I've played. Had to sell it when I lost my job years ago, regretted it, and now I'm slowly buying up parts to build a new one. Also WRT parts: it's really annoying how the Super Shorty forend is only available with the gun.

Hey XE, your channel is awesome. What adapter do you use to put on your paintball tank? I use soda stream cans, my adapter is giving up on me lol.. thanks!

Curious to see what your thoughts are on the Farsan/Hawsan Double Barrel converted to APS Shells. Sure you don't have repeating firepower but the mechanism is pretty reliable and being able to fire two shells simultaneously makes those quick corner peaks more devastating. Helps to learn how to load it like the competition shooters that basically load it like Doom Slayer.

What did you use to carry around your shells when you were using the Martini Henry and Hawsan?

is it compatible with real lsteel aftermarket furniture like magpul 870 accessories?

what is that folding stock called?

Has anyone had issues with having one shipped to the US? I've heard customs can seize yours and shops like Evike only carry the MK2.

can u make a slug using some hard foam or sonthing?

would love to see you do a review on the kwa mp7 and usp

where can i buy one in US?

I'm in UK and just bought your loading tool from shapeways...looks great..I'm a noob can you help and recommend a Co2 adapter..I bought paintball tanks based on your recommendation

Fun fact, it was not Taiwanese criminal that messed with the aps m870, it was the police that did the screwing around, so that they can get promoted by "confiscating firearms" and meeting thier police productively quota(yes, in Taiwan police have to deal with a certain amount of crimes per year to keep thier jobs😂). If anyone would like to know more about the story I'll reply in the comments.

nice

great Vid!. if I may ask what kind of shirt/jacket are you wearing at 30:40 ?? if I may ask,

I had to do a double take when you said mk3

do you happen to know what happened to the KS-23 you guys made?

babe new explosives enterprises just dropped

If i get it i feel like it would only be a wall hanger 😢

m8, those shades... dare to tell us what brand??

Nice replica!

Is it possible to modify a real steel 870 to take APS shells? Either the gas shells or the Mk2 shells?

What about Dominator DM870?

man I wish there was a viable shell ejection option. Is the pps shotgun bettter?

couldnt you use an actual shotgun but put the airsoft shells into it assuming they have the same diameter and load correctly

I have no interest in air soft, but this looks as if it would make an excellent replica for low budget films.

Neat

The APS shotgun is so realistic, if you have the budget. There is a steel kit on the market many years ago, and with some machine customize and install factory Remington 870 parts, can load and fire real 12ga. Don't ask why I know

One shell only, please xD

Well I've heard that the mod was done by police themself

29:29 LOL

Something tells me this is illegal in Canada 😂

"But since my wife collects combat shotguns" Wait what

The 870 was introduced in 1950. Idk why people keep saying 51. "Hurr durr source" I own one a first year first month production 870.

I don't think you should start off with replacing the internals with real steel ones. How can we learn about the gun's reliability then? Otherwise excellent

Just got one of these, and this is the perfect video to watch if you do get one, but i do have to correct you, in some parts of the US this is no toy, its a little crazy for you to say this no offense haha! I'm in Law Enforcement and also a firearms instructor for my home town and in my state this is actually considered a firearm and most places around me aren't the same obviously but they are never considered toys because the line of work im in i've seen some nasty stuff done by these believe it or not, but still a great video, and that real 870 Police is beautiful by the way ;) I have something similar for my car gun, but its obviously a more modern Remington 870 Tactical with Picatinny rails for a flashlight and a shell holder on the buttstock for 5 more rounds

Great reviews- but god, clean the dog hair out of your guns hahaha

Major subtle wife flex...

Neat
